Volute Casing Centrifugal Pumps according to EN 22858, ISO 2858 with Magnetic Drive Series CNH-M Usage For pumping toxic, volatile, explosive or other fluids harmful to the environment which call for service of hermetically tight pumps without shaft seal. The liquids must not chemically attack the pump / magnetic coupling materials. Design/Construction/Mounting Horizontal volute casing centrifugal pump with axial inlet, single stage, single entry in back pull out design with magnetic drive. The pump dimensions and the hydraulic coverage corresponds to DIN EN 22858 / ISO 2858. External bearing with either grease lifetime lubricated antifriction bearings. Arranged on the outer magnetic rotor supported in antifriction bearings are rows of permanent magnets. Separated by the stationary can the inner rotor with analog magnet equipment is inserted into the outer magnetic rotor. The inner rotor, together with the impeller, is arranged on the pump shaft supported in slide bearings. Torque transmission is contactless via the magnetic field lines between the outer and inner magnetic rotors. The inner rotor is supported in exceptional solid silicone carbide slide bearings (axial-radial bearing) which hydrodynamically absorb all hydraulic forces and shocks within the entire characteristics range. Performance data at 50 Hz Q up to 650 m³/h pd up to 25 bar H up to 145 m DNd from 25 to 200 mm t up to 170 C Nominal output of magnetic drive: P up to 48 KW at 1450 1/min P up to 96 KW at 2900 1/min Please take notice of the pressure/temperature limits in dependence of the material. Inlet pressure plus maximum delivery head (= 0-flow) must not exceed the stated value. Special low-temperature version on request. The mentioned performance data are only to be viewed as a product / performance overview. The exact operating limits are specified in the quotation and / or in the order acknowledgment. Recommended Minimum For actual flow rates, please see hydraulic coverage and / or individual hydraulic curves. As a protection against overheating when operating at low flow rates, a minimum flow rate is to be maintained according to the following formula: Qmin. = 0,3 x Q opt Flanges Flange dimensions according to DIN EN 1092-1 PN 16 / PN 25 and DIN EN 1092-2 PN 25. Other flange dimensions are possible. Drive By serial three-phase squirrel-cage induction motor. Up to 2,2 kw, 230/400 V, from 3 kw 400/690 V, IP55. Pressure and temperature limits as influenced by the casing material.

Bearing Pump side: Sleeve bearing, conveyance fluid lubrication. Drive side: ball bearing, oil or grease lubricated. Dismantling the insert unit If using a shaft coupling with a spacer the insert unit can be taken out on the drive side without taking off the volute casing and the motor off the base plate or the pipe lines off the volute casing. Dismounting of motor and drive unit can take place without tension release of system and draining. Shaft coupling and accidental contact protection Torsionally flexible shaft coupling according to DIN 740 with or without a spacer. A coupling guard as contact protection according to DIN EN 294 (DIN 31001) is included, if the delivery contains pump, base plate and shaft coupling. Explosion protection The pump fulfils the requirements according to EC Explosion Protection Directive 94/9EG (ATEX 100a) for equipment and equipment group II, category 2 G. Categorisation into temperature classes according to EN 13463-1 depends on the temperature of the pumped medium. The max. permissible temperature of the pumped medium for the respective temperature classes are shown in the below table: Danger classification Temperature classification according to EN 13463-1 Maximum fluid temperature T4 97 C II 2G/ EEx c/b T3 170 C II 3G/ EEX c T2 170 C T1 170 C Fire protection type b = monitoring of ignition sources Fire protection type c = safe design The temperatures mentioned above correlate with a maximum speed of 2900 1/min, a maximum ambient temperature of 40 C and the can material Hasteloy. Can materials with abnormal physical characteristics only may be used after consultation with Allweiler AG. Note: In case of the operation of a category 2 pump, the unacceptable heating of the pump surfaces caused by a possible operational fault must be prevented by a control mechanism. In case of an operation with know parameters (Q, H, <, D = const.), a pump performance controller can be supplied with the pump to detect any operational faults. Units: Only drives may be used, which correspond to the requirements according to EC Explosion Protection Directive 94/9EG.
